Your surgeon is a dope. Study spinal anatomy a little bit and you'll see that the elongated position of a road bike is quite healthy for a normal spine.


Bumping around happens during running, weight lifting, off-balance and off-axis awkward motions, and while riding in a more upright position.


Consult a physical therapist who is experienced with spinal injury recovery and he/she will be able to guide you. You Brits have "universal care", right?
